Claims19
A packaging material comprising
- a plurality of magnetisable portions thereon comprising at least one spot per package to be formed from the packaging laminate, and
- a magnetic mark providing a magnetic field pattern in the at least one magnetisable portion and being aligned with a preparation feature associated with an operation to be made to finish packages, respectively, wherein the magnetisable portion and the magnetic mark is positioned on the material such that relative speed between the material and means for reading or writing the magnetic mark is constant during reading or writing, respectively.
A packaging material comprising a plurality of magnetic marks printed thereon comprising at least one magnetic mark per package to be formed from the packaging material, said at least one magnetic mark being aligned with a preparation feature associated with an operation to be made to finish packages, wherein said at least one magnetic mark is positioned on the material such that relative speed between the material and means for reading the magnetic mark is non-zero, during reading.
